If the router doesn't have an RSP7000, I would highly doubt that it 
would have a VIP2.  The VIP2 won't work with the RP.  The only VIP-like 
board I know of that works with the RP is the FEIP.

Check.  The machine might have an RSP7000 in it, in which case you'd be 
in good shape.  The RSP7000 is two boards, unlike the RP.  There is a 
chassis interface board that sits in the SP slot, in place of an SP or SSP.

An RP+SSP will have trouble outpacing a PCI PC.  Probably even with a 
processor as old as that.  It is only capable of passing 15Mbps in 
Fast/CEF mode.  The RSP7000 can pass 112Mbps, and a VIP2-50 can pass an 
additional 72Mbps that doesn't need to pass through the main bus, 
provided that the traffic is moving from one PA slot to the other on the 
same VIP.

Of course, you *really* want to make sure you're not going to be using 
process switching, as the RP can only pass 1.3Mbps and the RSP7000 can 
only pass 2.6Mbps.  dCEF is your friend on these boxes.

Peace...  Sridhar
